Obama: We Must Create a 'World That is Worthy of Our Children'

“Accepting this challenge will not reward us with moments of victory that are clear or quick,” he said. “Our progress will be measured differently—in the suffering that is averted, and a planet that’s preserved … but the knowledge that the next generation will be better off for what we do here—can we imagine a more worthy reward than that? Passing that on to our children and our grandchildren, so that when they look back and they see what we did here in Paris, they can take pride in our achievement. Let that be the common purpose here in Paris. A world that is worthy of our children.”
